A reinforcing plate in a rectangular plate structure is arranged on the upper side face of an upper beam flange of a steel frame beam; bolt holes are reserved in the reinforcing plate; the reinforcing plate is fixedly mounted on the upper side face of the upper beam flange by high strength bolts; a reinforcing axillary plate is arranged on the lower side face of a lower beam flange; reinforcing axillary plate straight segments are arranged at the two ends of the reinforcing axillary plate respectively; a reinforcing axillary plate oblique segment is arranged in the middle of the reinforcing axillary plate; bolt holes are reserved in the reinforcing axillary plate straight segments; the two ends of the reinforcing axillary plate are fixedly mounted between the lower beam flange and a column inner side flange by high strength bolts; the folded plate type reinforcing axillary plate is an integral plate piece; the reinforcing axillary plate is in a non-welded fixing structure; a stiffening rib corresponding to a beam web of the reinforcing axillary plate straight segment is vertically arranged between the lower beam flange and the upper beam flange; and the asymmetric reinforcing axillary plate bolted connection device is simple in structure, convenient to mount, low in manufacturing cost, strong in shock resistance, good in delay property, and convenient to mount and use on a construction site.

Description

A kind of asymmetric reinforcement armpit crab bolt linkage
Technical field:
The invention belongs to the building engineering equipment technical field, relate to time-delay shock-resistant node structure, particularly a kind of asymmetric reinforcement armpit crab bolt linkage that the asymmetric reinforcement armpit of a kind of steel frame beam-ends plate hight strength bolts connects.
Background technology:
At present, the general employing of beam-to-column!moment connection node is welded to connect, brittle fracture very easily occurs under severe earthquake action, existing settling mode generally has two kinds: the one, and flange of beam is carried out local weaken (RBS node) near the failure position of beam column join domain weld seam is moved outward, be called for short weakening type node; The 2nd, at the local beam section that strengthens of join domain, improve ductility of joint, be called for short reinforced node; This dual mode shifts out plastic hinge from the welding node zone, avoid plastic hinge to appear at the relatively poor welding point place of toughness, guarantee that node has enough ductility, but weakening type node is to weaken beam section, reducing Load-bearing capacity of beam is the purpose of design that cost reaches plasticity under the severe earthquake action, there is larger potential safety hazard, reinforced node adopts the beam-ends haunch, the types such as floor heavier-duty and board-like reinforcement, reinforced connected node all adopts the form of being welded to connect, and the welding residual stress that the attachment weld place produces and distortion will produce totally unfavorable impact to the anti-seismic performance of node.
Summary of the invention:
The object of the invention is to overcome the shortcoming that prior art exists, seek to design the asymmetric reinforcement armpit of a kind of steel frame beam-ends plate hight strength bolts linkage that provides, make it under the violent earthquake effect, force the plastic hinge of beam-ends welded seam area, satisfy Seismic Design Requirements, welding stress and the welding deformation of avoiding reinforced node to exist.
To achieve these goals, agent structure of the present invention comprises oblique section of reinforcement armpit plate, strengthens the inboard edge of a wing of armpit plate straightway, high-strength bolt, stiffener, stiffening rib, beam top flange, lower flange of girder edge, reinforcement armpit plate and pillar; Be shaped with the stiffener of Rectangular Plate Structure on the upper side of the beam top flange of steel-frame beam, reserve on the stiffener and be shaped with the bolt hole that cooperates with high-strength bolt, stiffener is fixedly mounted on the upper side of beam top flange by the high-strength bolt run-in index; Being shaped with two ends on the downside of the lower flange of girder edge of steel-frame beam is the reinforcement armpit plate of flap type structure, the two ends of strengthening the armpit plate are shaped with respectively strengthens armpit plate straightway, middle for strengthening oblique section of armpit plate, reserve respectively on the reinforcement armpit plate straightway and be shaped with the bolt hole that cooperates with high-strength bolt, the two ends of strengthening the armpit plate are fixedly mounted between lower flange of girder edge and the inboard edge of a wing of pillar by high-strength bolt respectively; The reinforcement armpit plate of flap type is whole plate, forms behind the hot bending to strengthen oblique section of armpit plate and strengthen armpit plate straightway, and strengthening the armpit plate is the no-welding type fixed structure, avoids the generation of residual stress and distortion; The corresponding web position of strengthening armpit plate straightway vertically is shaped with together stiffening rib between lower flange of girder edge and the beam top flange, plastic hinge is moved to the end of strengthening the armpit plate.
The present invention compared with prior art, the reinforcement armpit plate of steel frame beam-ends adopts high-strength bolt to connect and realizes plastic hinge, avoid welding the welding stress of reinforced node and welding deformation to the adverse effect of node mechanical property, it is simple in structure, easy for installation, cost of manufacture is low, and shock resistance is strong, time delay is good, and constructability is on-the-spot to be installed and use.
Description of drawings:
Fig. 1 is agent structure principle schematic of the present invention.
The specific embodiment:
Below in conjunction with accompanying drawing and by embodiment to being described further.
Embodiment:
The agent structure of the present embodiment comprises strengthens oblique section 1 of armpit plate, reinforcement armpit plate straightway 2, high-strength bolt 3, stiffener 4, stiffening rib 5, beam top flange 6, lower flange of girder edge 7, reinforcement armpit plate 8 and the inboard edge of a wing 9 of pillar; Be shaped with the stiffener 4 of Rectangular Plate Structure on the upper side of the beam top flange 6 of steel-frame beam, reserve on the stiffener 4 and be shaped with the bolt hole that cooperates with high-strength bolt 3, stiffener 4 is fixedly mounted on the upper side of beam top flange 6 by high-strength bolt 3 run-in indexs; Being shaped with two ends on the downside of the lower flange of girder edge 7 of steel-frame beam is the reinforcement armpit plate 8 of flap type structure, the two ends of strengthening armpit plate 8 are shaped with respectively strengthens armpit plate straightway 2, middle for strengthening oblique section 1 of armpit plate, reserve respectively on the reinforcement armpit plate straightway 2 and be shaped with the bolt hole that cooperates with high-strength bolt, the two ends of strengthening armpit plate 8 are fixedly mounted between lower flange of girder edge 7 and the inboard edge of a wing 9 of pillar by high-strength bolt 3 respectively; The reinforcement armpit plate 8 of flap type is whole plate, forms behind the hot bending to strengthen oblique section 1 of armpit plate and strengthen armpit plate straightway 2, and strengthening armpit plate 8 is the no-welding type fixed structure, avoids the generation of residual stress and distortion; The corresponding web position of strengthening armpit plate straightway 2 vertically is shaped with together stiffening rib 5 between lower flange of girder edge 7 and the beam top flange 6, plastic hinge is moved to the end of strengthening armpit plate 8.
